ArtiaX error after closing all models and opening new particle list

[goddard@…]

The following bug report has been submitted:
Platform:        macOS-10.16-x86_64-i386-64bit
ChimeraX Version: 1.4 (2022-06-03 23:39:42 UTC)
Description
Using ArtiaX to look at a set of particles (no tomogram) with surfaces, then I used the command "close", then tried to open a new particle list and got this error.  I aloso notice that the ArtiaX particle list panel at the left still has the closed motivelist_RNAP.em file shown.

Closing the main ArtiaX model is not caught and handled correctly,  
causing the tool to fail (it expects the root model to persist).

I'll close this ticket since you don't have an account on our system to close it yourself.

It will be good to make new Toolshed ArtiaX releases when you fix bugs that multiple users are likely to run into. Not sure if this is such a bug. When making a new release on Toolshed it does not go through an approval process so it should just take some minutes to upload a new *.whl file.
